Purpose: Color Doppler Imaging in patients with orbital compression frequently shows apparent contradictive results. The aim of the recent study was to analyze Color Doppler Imaging examinations performed in cases of orbital compression with the objective to correlate defined morphological findings with typical Color Doppler Imaging results and to evaluate the method for orbital diagnostics.
Method: A retrospective analysis of Color Doppler Imaging examinations in patients with orbital compression diagnosed by radiological and clinical examination and anamnesis was performed. Five patients with orbital tumors and five patients with orbital-apex-compression-syndrome after cranial-cerebral-injury were included. The Color Doppler Imaging contained the examinations of the Ophthalmic Artery, the Superior Orbital Vein, the Short Ciliary Arteries, the Central Retinal Artery and Vein. Additionally, the gained results were compared to those in patients with arterio-venous fistulas to demonstrate the detailed similarities and differences.
Results: In correlation to the extent and localization of the morphological finding and the grade of compression following Color Doppler Imaging results were observed:
1. low level orbital compression: retrograde outflow in the Superior Orbital Vein, negative Valsalva Maneuver, orthograde perfusion of the Ophthalmic Artery
2. high level orbital compression with localization in the orbital apex region and possible Op
